Injini ephambili yovavanyo lokuchaneka: ukusetyenziswa kwee-motor ze-micro stepper kwii-adapters zovavanyo lweenaliti ze-elektroniki

Kwicandelo lokwenziwa kwe-elektroniki okukhawulezayo nokuchanekileyo, ii-adaptha zovavanyo lweenaliti ze-elektroniki zisebenza njengabagcini-masango abaqinisekisa umgangatho wee-PCB, iitships, kunye neemodyuli. Njengoko isithuba se-pin yecandelo sisiya sisiba sincinci kwaye ubunzima bovavanyo busanda, iimfuno zokuchaneka nokuthembeka kuvavanyo zifikelele kumanqanaba angazange abonwe ngaphambili. Kolu tshintsho lokulinganisa ngokuchanekileyo, ii-motor ze-micro stepper zidlala indima ebalulekileyo njenge "zihlunu ezichanekileyo". Eli nqaku liza kujonga indlela le core yamandla incinci esebenza ngayo ngokuchanekileyo kwii-adaptha zovavanyo lweenaliti ze-elektroniki, iqhuba uvavanyo lwe-elektroniki lwanamhlanje kwixesha elitsha.

一.Intshayelelo: Xa ukuchaneka kovavanyo kufuneka kube kwinqanaba le-micron

Iindlela zovavanyo zemveli azanelanga kwiimfuno zovavanyo lweephakheji zanamhlanje ze-micro-pitch BGA, QFP, kunye ne-CSP. Umsebenzi ophambili we-adapter yovavanyo lwenaliti ye-elektroniki kukuqhuba amashumi okanye amawaka eeprobe zovavanyo ukuseka unxibelelwano oluthembekileyo lomzimba nombane kunye neendawo zovavanyo kwiyunithi evavanywayo. Nakuphi na ukungalungelelani okuncinci, uxinzelelo olungalinganiyo, okanye unxibelelwano olungazinzanga kunokukhokelela ekusileleni kovavanyo, ukugweba kakubi, okanye nomonakalo wemveliso. Iimoto ze-Micro stepper, ezinolawulo lwazo lwedijithali olukhethekileyo kunye neempawu ezichanekileyo, ziye zaba sisisombululo esifanelekileyo sokujongana nale mingeni.

一.Indlela yokusebenza engundoqo yemoto ye-micro stepper kwi-adaptha

Ukusebenza kwe-micro stepper motor kwi-electronic needle test adapter akuyonto ilula ukujikeleza, kodwa luchungechunge lweentshukumo ezichanekileyo nezilawulwayo. Ukuhamba kwayo kungahlulwahlulwa ngokwamanyathelo aphambili alandelayo:

1. Ulungelelwaniso oluchanekileyo kunye nokubekwa kwindawo yokuqala

Ukuhamba komsebenzi:

Ukufumana imiyalelo:Ikhompyutha yomncedisi (umncedisi wovavanyo) ithumela idatha yokulungelelanisa yecandelo eliza kuvavanywa kwikhadi lolawulo lokunyakaza, eliyiguqula ibe luchungechunge lwemiqondiso ye-pulse.

Intshukumo yokuguqulwa kwepulse:Ezi signali zepulse zithunyelwa kumqhubi we-micro stepper motor. Isignali nganye yepulse iqhuba i-motor shaft ukuba ijikeleze i-engile esisigxina - "i-engile yesinyathelo". Ngokusebenzisa ubuchwepheshe obuphambili be-microstepping drive, i-engile yesinyathelo epheleleyo inokwahlulwa ibe zii-microsteps ezingama-256 okanye nangaphezulu, ngaloo ndlela ifezekisa ulawulo lokufuduka kwinqanaba le-micrometer okanye kwinqanaba le-submicrometer.

Indawo yokusebenza:Injini, ngokusebenzisa iindlela zokudlulisa ezifana nezikrufu ze-lead ezichanekileyo okanye iibhanti zexesha, iqhuba inqwelo ethwele iiprobe zovavanyo ukuze ihambe kwiindiza ze-X-axis kunye ne-Y-axis. Inkqubo ihambisa ngokuchanekileyo uluhlu lweprobe ukuya kwindawo engentla kwendawo ukuze ivavanywe ngokuthumela inani elithile leepulses.

2. Ulawulo loxinzelelo olulawulwayo kunye noxinzelelo

Ukuhamba komsebenzi:

Uqikelelo lwe-Z-axis:Emva kokugqiba ukubeka iplane, i-micro stepper motor enoxanduva lokuhamba kwe-Z-axis iqala ukusebenza. Ifumana imiyalelo kwaye iqhube yonke intloko yovavanyo okanye imodyuli enye yeprobe ukuba ihambe ngokuthe nkqo iye ezantsi nge-Z-axis.

Ulawulo lokuhamba oluchanekileyo:Injini icinezela phantsi kakuhle ngamanyathelo amancinci, ilawula ngokuchanekileyo umgama wokuhamba wepress. Oku kubalulekile, njengoko umgama omfutshane kakhulu wokuhamba unokubangela ukuba unxibelelwano lube lubi, ngelixa umgama omde kakhulu wokuhamba unokucinezela ispring yeprobe kakhulu, nto leyo ebangela uxinzelelo olugqithisileyo kunye nomonakalo kwi-solder pad.

Ukugcina iTorque ukuze Ugcine Uxinzelelo:Xa iprobe ifikelela kubunzulu boqhagamshelwano olucwangcisiweyo kwindawo yovavanyo, i-micro stepper motor iyayeka ukujikeleza. Kule ndawo, i-motor, ene-torque yayo ephezulu yokubamba, iya kutshixwa ngokuqinileyo endaweni yayo, igcine amandla okuhla ahlala ehleli kwaye ethembekileyo ngaphandle kwesidingo sombane oqhubekayo. Oku kuqinisekisa uzinzo lonxibelelwano lombane kulo lonke umjikelo wovavanyo. Ingakumbi kuvavanyo lwesignali olusebenzisa amaxesha amaninzi, uqhagamshelwano oluzinzileyo loomatshini lusisiseko sokuthembeka kwesignali.

3. Ukuskena okunamanqaku amaninzi kunye novavanyo oluntsonkothileyo lwendlela

Ukuhamba komsebenzi:

Kwii-PCB ezintsonkothileyo ezifuna ukuvavanywa kwezinto kwiindawo ezahlukeneyo okanye kwiindawo eziphakamileyo ezahlukeneyo, ii-adapters zidibanisa ii-motor ezininzi ze-micro stepper ukuze zenze inkqubo yokuhamba ene-axis ezininzi.

Le nkqubo iququzelela intshukumo yeemoto ezahlukeneyo ngokwenkqubo yovavanyo ecwangcisiweyo kwangaphambili. Umzekelo, kuqala ivavanya iNdawo A, emva koko iimoto ze-XY zihamba ngokuhambelana ukuze zihambise uluhlu lweprobe ziye kwiNdawo B, kwaye i-Z-axis motor icinezele phantsi kwakhona ukuze ivavanywe. Le ndlela "yovavanyo lokubhabha" iphucula kakhulu ukusebenza kakuhle kovavanyo.

Kuyo yonke le nkqubo, amandla okukhumbula indawo echanekileyo yemoto aqinisekisa ukuchaneka kokubeka indawo rhoqo, okususa iimpazamo eziqokelelweyo.

一.Kutheni ukhetha ii-micro stepper motors? - Iingenelo ezingasemva kwendlela yokusebenza

Indlela yokusebenza echanekileyo ekhankanyiweyo apha ngasentla ivela kwiimpawu zobugcisa ze-micro stepper motor ngokwayo:

Ukwenziwa kwedijithali kunye nokuvumelanisa iPulse:Indawo yemoto ihambelana ngokungqongqo nenani lee-input pulses, nto leyo evumela ukuhlanganiswa okungenamthungo neekhompyutha kunye nee-PLC ukuze kulawulwe ngokupheleleyo ngedijithali. Lukhetho olufanelekileyo lovavanyo oluzenzekelayo.

Akukho mpazamo eqokelelweyo:Phantsi kweemeko ezingadingi ukulayisha kakhulu, impazamo yenyathelo lemoto ye-stepper ayiqokeleli kancinci kancinci. Ukuchaneka kwentshukumo nganye kuxhomekeke kuphela ekusebenzeni okuqhelekileyo kwemoto kunye nomqhubi, okuqinisekisa ukuthembeka kovavanyo lwexesha elide.

Ulwakhiwo oluncinci kunye noxinano oluphezulu lwe-torque:Uyilo oluncinci luvumela ukuba lufakwe lula ngaphakathi kwezinto zovavanyo ezincinci, ngelixa lubonelela nge-torque eyaneleyo yokuqhuba uluhlu lweprobe, lufezekisa ibhalansi epheleleyo phakathi kokusebenza kunye nobukhulu.

一.Ukujongana nemingeni: Iteknoloji yokuphucula ukusebenza kakuhle komsebenzi

Nangona ziluncedo kakhulu, kwiindlela ezisebenzayo, ii-motor ze-micro stepper nazo zijongene nemingeni efana nokuqaqamba, ukungcangcazela, kunye nokulahleka kwenyathelo okunokwenzeka. Ukuqinisekisa ukusebenza kwayo okungenasiphako kwiiadaptha zovavanyo lweenaliti ze-elektroniki, eli shishini lisebenzise ezi ndlela zilandelayo zokuphucula:

Ukusetyenziswa okunzulu kwetekhnoloji ye-micro-stepping drive:Ngokusebenzisa i-micro-stepping, ayiphuculwanga nje kuphela isisombululo, kodwa okubaluleke ngakumbi, intshukumo yemoto iyagudiswa, nto leyo enciphisa kakhulu ukungcangcazela kunye nengxolo ngexesha lokurhubuluza ngesantya esiphantsi, nto leyo eyenza ukuba unxibelelwano lwe-probe luhambelane ngakumbi.

Intshayelelo yenkqubo yolawulo oluvaliweyo:Kwezinye izicelo ezifunwa kakhulu, ii-encoders zongezwa kwiimoto ezincinci ukuze zenze inkqubo yolawulo oluvaliweyo. Inkqubo ijonga indawo yokwenyani yemoto ngexesha langempela, kwaye yakuba ifunyenwe ingasebenzi kakuhle (ngenxa yokuxhathisa kakhulu okanye ezinye izizathu), iya kuyilungisa ngoko nangoko, idibanisa ukuthembeka kolawulo oluvulekileyo kunye nesiqinisekiso sokhuseleko senkqubo evaliweyo.

一.Isiphelo

Ngamafutshane, ukusebenza kwee-micro stepper motors kwii-adapters zovavanyo lweenaliti ze-elektroniki kusebenza njengomzekelo ogqibeleleyo wokuguqula imiyalelo yedijithali ibe ziintshukumo ezichanekileyo kwihlabathi elibonakalayo. Ngokwenza uthotho lwezenzo ezilawulekayo ngokuchanekileyo, kubandakanya ukufumana ii-pulses, ukwenza iintshukumo ze-micro-step, kunye nokugcina indawo, yenza imisebenzi ebalulekileyo yokulungelelanisa ngokuchanekileyo, ukucinezela okulawulwayo, kunye nokuskena okuntsonkothileyo. Ayisiyonto iphambili yokwenza kuphela ukufezekisa ukuzenzekela kovavanyo kodwa ikwayinjini ephambili yokuphucula ukuchaneka kovavanyo, ukuthembeka, kunye nokusebenza kakuhle. Njengoko izinto ze-elektroniki ziqhubeka nokuguquka ziye kwi-miniaturization kunye noxinano oluphezulu, itekhnoloji yee-micro stepper motors, ngakumbi itekhnoloji yayo yokulawula i-micro-stepping kunye ne-closed-loop, iya kuqhubeka nokuqhubela phambili itekhnoloji yovavanyo lwe-elektroniki kwiindawo ezintsha.
